Builders · Holsworthy
Builders in Holsworthy, for stone farmhouses, market-town streets and everything off the mains.
Holsworthy sits right on the Devon and Cornwall border, a working market town surrounded by agricultural holdings rather than commuter estates. That means most jobs we take on here involve older stone and cob buildings, land that has never seen a mains drainage connection, and clients who want a builder who understands a farmyard as well as a sitting room.
Local knowledge
Building work around Holsworthy
Holsworthy's identity is agricultural first and residential second. The town itself has a compact core of stone and rendered buildings around the square, but the vast majority of the properties we are asked to look at sit out along the lanes off the A3072 towards Bude, or on the roads running north towards Bradworthy and south towards Pyworthy: working farms, smallholdings and the farmhouses that go with them.
The building stock reflects that history. Cob and stone farmhouses are common, many extended piecemeal over a century or more as the farm grew, with later additions in block or brick sitting alongside the original cob walls. Working with that mix means understanding which walls breathe and which don't, where a damp problem is actually a ventilation problem, and how to tie a new extension into an old wall without trapping moisture behind modern render or plasterboard. We've done enough of this work across North Devon to know that guessing is expensive; every cob wall gets assessed on its own terms before we start pricing.
Off-mains drainage is the other constant. A large share of the properties around Holsworthy rely on septic tanks or treatment plants rather than a mains sewer connection, and that changes how we approach almost any extension or new bathroom. Adding a bedroom or a second bathroom can mean checking whether the existing system has the capacity, whether building control will require an upgrade to a modern treatment plant, and where a soakaway or drainage field can go given the land available. It's not a complication we shy away from; it's routine here, and it needs to be priced properly from the first estimate rather than discovered halfway through the job.
The A3072 itself runs straight through the town and links out towards Bude on one side and Hatherleigh on the other, which keeps Holsworthy well connected despite its rural setting. Within the town, streets and yards can be tight, and a lot of the older stone terraces and cottages near the centre have limited off-street parking or narrow rear access: something we plan for at quote stage so a skip, a cement mixer or a delivery lorry isn't a surprise on day one.
Agricultural buildings themselves are a regular part of the work too. Barn conversions, redundant stone linhays being brought back into use as living space or workshops, and general repairs to farm buildings that have taken decades of weather without much attention. These jobs often combine groundworks, structural alterations and carpentry in one project, and having all of those skills in-house rather than split across three separate firms keeps the job coordinated and keeps you dealing with one person rather than three.

Why us
Why Holsworthy clients choose us
Holsworthy sits at the edge of our usual patch, which means we're realistic with you about travel time and we plan visits efficiently rather than pretending we're around the corner.
One project manager, start to finish
Adam Harrison quotes the job, runs the site and answers your calls personally; there's no account manager relaying messages between you and the people actually doing the work.
Genuine off-mains experience
We treat septic tank and treatment plant capacity as part of the design brief for any extension, not an afterthought raised after building control gets involved.
In-house trades that talk to each other
Groundworks, brickwork, carpentry, plastering and tiling are all handled by our own team of five, so an extension against an old cob wall is planned by the people actually building it.
Honest about distance
Holsworthy is roughly 40 minutes from our base at Langtree via the A3072 and A388. We tell you that upfront and build site visits around it, rather than promising a speed we can't deliver.
Common issues
What catches people out on Holsworthy jobs
Most problems on farmhouse and rural projects around Holsworthy come from the same handful of causes, and they're avoidable if they're priced and planned for from day one.
Extending without checking drainage capacity
A new bedroom or bathroom adds to the load on a septic tank or treatment plant that may already be at or near capacity. Building control will ask the question eventually; better to ask it before you commit to a design than after the extension is half built and the drainage fails the test.
Sealing cob walls with the wrong materials
Cob and traditional stone walls need to let moisture pass through them. Cement render or standard gypsum plaster applied to an old wall traps that moisture instead, and the damp shows up somewhere new a year or two later, usually at the worst possible spot, like behind a fitted kitchen. Lime-based systems cost a little more upfront and save a great deal of grief later.
Underestimating access for materials
Farm tracks and narrow lanes around Holsworthy aren't always built for a full-size delivery lorry or a large skip. We check access as part of the estimate, not as a surprise when the first load of blocks turns up and can't get down the lane.
Treating a barn conversion like a standard extension
Converting a stone linhay or agricultural barn brings its own structural questions: historic roof structures, uneven floor levels and openings that were never meant to be doors or windows. A structural survey before pricing avoids expensive surprises once the roof comes off.

Questions
Straight answers before you commit
If your question isn't here, ring Adam directly; you'll get the same straight answer on the phone.
Do you cover Holsworthy and the surrounding farms?
Yes. Holsworthy and the farms and hamlets around it, towards Bude, Bradworthy and Pyworthy, are a regular part of our patch, even though it sits towards the edge of our usual North Devon coverage from Langtree. We're upfront that it's roughly a 40-minute drive, and we plan visits accordingly rather than promising to be there in ten minutes.
How quickly can you get out to look at a job near Holsworthy?
We arrange the initial look as soon as the diary allows, though for jobs further out towards the Cornwall border we sometimes group visits to keep travel efficient. We'll always give you a realistic date rather than an optimistic one, and Adam personally carries out the visit.
What does building work cost around Holsworthy?
Cost depends heavily on the property: cob and stone farmhouses often need specialist treatment that a standard brick house wouldn't, and off-mains drainage can add cost that a mains-connected property never sees. Your initial estimate is free; a full itemised quote carries a fee, refunded in full if you go ahead, so you know the real figure before committing.
Can you deal with a job that needs urgent attention?
We're not a 24-hour emergency callout service, but if something on an existing project or a recent job needs urgent attention, call and we'll fit you in as quickly as the diary allows. For genuine emergencies such as burst pipes or structural danger, a specialist emergency trade is often the faster first call.
Is the work guaranteed?
Every job carries our 12-month no-quibble workmanship guarantee, and new builds come with a 10-year structural warranty plus a 12-month snagging process. We also carry £5m public liability and £10m employers' liability insurance.
Do you handle planning permission and building control for Holsworthy properties?
Yes. Many of the older or agricultural buildings around Holsworthy sit in areas where planning conditions or listed status apply, and we'll tell you honestly if that's the case. Notifiable work can go through a private building control company for a fee, or through your council , we'll advise which suits your property.
What about access for skips, deliveries and machinery?
Farm tracks and narrow town streets around Holsworthy aren't always built for full-size delivery vehicles. We check access as part of the site visit and plan deliveries, skip placement and any machinery around what your particular property allows.
Can you work on cob and stone farmhouses?
Yes, this is a large part of what we do around Holsworthy. Cob and stone need different treatment to modern block: different plaster systems, different approaches to damp and different care when opening up walls structurally. We assess the building fabric before pricing rather than treating it like standard construction.
Do you deal with septic tanks and treatment plants?
Regularly. Groundworks and drainage installation, including septic tank and treatment plant work, sits in-house with our team. Any extension or extra bathroom is checked against existing drainage capacity before we finalise a design.
How long does a typical extension or renovation take near Holsworthy?
A single-storey extension typically runs several weeks to a few months depending on size, drainage work required and weather during groundworks; a full farmhouse renovation can run considerably longer. You'll get a realistic programme with your detailed quote, not just a headline figure.
